ABSTRACT
Pancreaticoduodenectomy is established as the procedure of choice for malignant tumor pathologies of the head of the pancreas or ampulla, where the patient's life prognosis is low. Complications after pancreaticoduodenectomy (e.g. pancreatic fistulas, hemorrhages, or intra-abdominal collection) are well described in the literature and are generally acute. However, there is still a small risk for late complications (e.g. pancreatitis, pancreatic insufficiency), and due to its low incidence, there has not been a consensus on the treatment. We present the case of an 18-year-old female with recurrent bouts of acute pancreatitis as a late complication of a pancreaticoduodenectomy plus pancreatojejunal anastomosis due to a pseudopapillary tumor of the pancreas. The complication was managed though surgical revision consisting of dilation and stent placement in the stenosis. The patient had an adequate postoperative evolution without further complications. Despite the advances in the surgical field, pancreaticoduodenectomy represents a highly complex surgery with high morbidity and mortality rates. The late complications of this surgery are under continuous study due to its low incidence associated with low patient survival.
ABSTRACT
INTRODUCTION AND IMPORTANCE: Littoral cell angioma is a rare solid spleen tumor with uncertain malignant potential. It is usually asymptomatic; therefore, its diagnosis is usually incidental. There are approximately 150 cases reported in the medical literature, but none of them in the Hispanic population. CASE PRESENTATION: We present a case of a 54-year-old woman who presented to our clinic with nonspecific abdominal pain. Imaging studies show a splenic mass with littoral cell angioma characteristics. The patient underwent an open splenectomy with subsequent histopathologic and immunohistochemical studies that confirmed the presence of a littoral cell angioma of a diameter of 8 × 4.5 × 3.5 cm. The patient was discharged after an uneventful postoperative recovery and was referred to the outpatient clinic for follow up. CLINICAL DISCUSSION: This case report highlights the close relationship between the littoral cell angioma, neoplasias, and autoimmune diseases. Even though LCA has a good prognosis, there is still the possibility of malignant transformation, especially when the spleen weighs 1500 g; our patient's sample pointed towards a benign pathology. LCA has a positive IHC for endothelial and histiocyte tissues. The IHC results of our patient were positive for CD34+ and CD68+, confirming the LCA diagnosis. CONCLUSION: Within red pulp spleen tumors, LCA should be highly considered as a differential diagnosis in all types of populations. In the case of a confirmed LCA, routine screening for neoplasias and autoimmune diseases should be performed.
ABSTRACT
La hepatolitiasis es un desorden de las vías biliares caracterizado por la presencia de cálculos en los conductos biliares intrahepáticos. Existen varios factores de riesgo asociados a esta patología, pero su complicación más temida es el desarrollo de un colangiocarcinoma. En el Ecuador no hay literatura sobre el manejo de esta patología y su pronóstico postoperatorio. Se presenta el caso de un paciente masculino de 50 años de edad, con un cuadro de dolor abdominal en epigastrio, acompañado de hiporexia y náusea, sin hallazgos relevantes en el examen físico. Se encontraron pruebas de función hepática alteradas y marcadores tumorales elevados, además, los estudios radiológicos evidenciaron dilatación de la vía biliar intrahepática, con litos en su interior. Se decidió realizar una hepatectomía izquierda y, posteriormente, el estudio histopatológico evidenció cambios sugestivos de displasia en los conductos intrahepáticos. El paciente es dado de alta con una evolución dentro de los parámetros esperados y es remitido a seguimiento por Consulta Externa. En conclusión, la hepatolitiasis es una condición que al no ser tratada puede desarrollar un colangiocarcinoma, aumentando el riesgo del paciente
Hepatolithiasis is a bile duct disorder characterized by the presence of stones in the intrahepatic bile ducts1. There are several risk factors associated with this pathology, but its most feared complication is the development of cholangiocarcinoma2. In Ecuador there is not published literature regarding the management and prognosis of this pathology. A 50-year-old male patient with a picture of abdominal pain in the epigastrium, accompanied by hyporexia and nausea, without relevant findings on the physical exam. Altered liver function tests and raised tumor markers were found, in addition, radiological studies showed dilation of the intrahepatic bile duct, with bile stones inside. A left hepatectomy was performed, and subsequently the histopathological study demonstrated suggestive dysplasia changes in the intrahepatic ducts. Patient is discharged with a positive evolution and is referred to clinic for further follow up. To sum up, hepatolithiasis is a condition that should promptly be treated to avoid the development of a cholangiocarcinoma, which could put in risk the patient's life.

El ameloblastoma es una neoplasia benigna de origen epitelial, localmente agresiva que afecta a la mandíbula. Se caracteriza por su crecimiento invasivo y su tendencia a la recurrencia. A continuación nosotros reportamos el caso de un ameloblastoma recurrente en la mandíbula. Además hemos hecho una revisión de los diferentes tipoos, histología y manejo de las lesiones así como planteamos una alternativa de reconstrucción mandibular inmediata en la rehabilitación del paciente.
